Pegmatites are texturally complex igneous rocks marked by some combination of coarse but
variable crystal size, mineralogical zonation, prominent anisotropy of crystal orientations …

Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

Zircon composition has great potential as a pathfinder for porphyry Cu±Mo±Au systems. The
present study used a large integrated laser ablation-inductively coupled plasma-mass …

Chondrite normalized rare earth element (REE) patterns of zircons generally have enriched
Ce values relative to La and Pr, and depleted Eu values relative to Sm and Gd. High Ce …

Biotite (sensu lato) is a widespread rock‐forming mineral in magmatic rocks that can be
stable in a broad range of pressure and temperature, but appropriate biotite thermometers or …

Silicic magma systems are of great scientific interest and societal importance owing to their
role in the evolution of the crust and the hazards posed by volcanic eruptions. MELTS is a …

Geophysical characterization of calderas is fundamental in assessing their potential for
future catastrophic volcanic eruptions. The mechanism behind the unrest of Long Valley …

Abstract High silica (> 70 wt.% SiO 2) granites (HSGs) are important carriers of highly
incompatible elements, thus, understanding their origin is relevant to understanding how the …

The application of the Ti-in-zircon thermometer to granitic rock requires consideration of a_
TiO _ 2 a TiO 2 and a_ SiO _ 2 a SiO 2 during zircon crystallization. Thermodynamic …
